“…Measurements were taken from the palmar side with digits fully stretched touching on a flat, hard surface and the 2nd to 5th digit adducted and the thumb slightly extended. 5 For each hand, 7 parameters related with hand dimensions and ratios were evaluated. Hand width, hand length, 3rd digit length and body height were measured with the method stated by Pheasent.…”

The human hand is unique in being free of habitual locomotor duty and devoted entirely to functions of manipulation. Its effectiveness in these activities is due to particular configuration of the bones and muscles which permits opposition of the pulp surface of the thumb to the corresponding surfaces of the other four finger tips in a firm grasp, together with a highly elaborated nervous control and sensitivity of the fingers.1 Hand is a very complex structure capable of not only a multitude of motor tasks but also of relaying sensory information about the temperature, the shape and texture of objects to the brain. 2The hand does not function in isolation, and is dependent on the integrity of the shoulder and elbow complexes to allow the appropriate positioning of the hand in space to complete the desired task. AbstractObjectives: This cross-sectional study was performed to compare hand anthropometric measurements and grip strength among different sports groups. Methods:The study group was composed of 145 basketball players, 133 volleyball players and 96 handball players aged between 9-18 years. A digital compass (Shan, 150 mm) with a resolution of 0.01 mm/0.0005 inch was used for hand anthropometric measurements and a digital hand dynamometer (Takei) was used for grip strength measurement. During measurements values for both hands were obtained. Eight parameters were evaluated for each hand. For statistical analyses One Way ANOVA for parametric conditions and Kruskal-Wallis Variance Analyses for subgroups which have nonparametric conditions were performed. The differences within the groups were evaluated with post hoc Bonferroni adjustment.Results: There were statistically significant differences for right and left hand width, right finger index, right hand length/height, left hand length/height values between basketball, handball and volleyball players. The differences between basketball and handball players were the reason for the aforementioned differences. There were statistically significant differences in right and left width, right and left third finger length, right and left hand grip strength values in females. These significances were caused by handball players. Conclusion:These findings suggest that different sports could constitute different effects on hand anthropometric measurements and grip strength and sex should be considered.

“…Ozgen ve ark. yaptıkları bir çalışmada mental retardasyonu bulunmayan otizmli çocuklarla sağlıklı çocuklardaki bazı minör fiziksel anomalileri ve bazı fiziksel özellikleri karşılaştırmışlar; ancak el boyu ve orta parmak boyu açısından sağlıklı çocuklar ve otizmli çocuklar arasında herhangi bir farklılık saptayamamışlardır (32).El genişliği, palmar uzunluk gibi parametreler kişinin el tercihi gibi çeşitli faktörlerden de etkilenebilmektedir (33). El parmak uzunluğu ve diğer morfolojik özelliklerin ölçümüyle yapılacak çalışmalarda bu gibi değişkenlere dikkat edilmelidir.…”

“…Parmak boyları elin palmar yüzünde bulunan proksimal bölgedeki bazal çizgi ile pulpa arasındaki mesafe ölçülerek hesaplanmış olup palmar uzunluk ise; bilekten 3. parmağın kökünün orta noktası arasındaki uzunluk ölçülerek bulunmuştur. 2.parmağın 4.parmağa oranı; her iki uzunluğun birbirine bölünmesi yolu ile bulunmuştur (33). Hasta ve kontrol grubunda tüm ölçümler 2 farklı araştırmacı tarafından yapılmış olup, bu iki değerin aritmetik ortalaması alınmış, tüm istatistiksel değerlendirmeler de bu aritmetik ortalamaya göre yapılmıştır…”

Bu çalışmanın verilerinin bir bölümü 28-30 Kasım 2013 tarihleri arasında Konya'da yapılan "Konya Otizm Günleri"nde sözel bildiri olarak sunulmuştur. Parmağa oranının (2d:4d) otizmde daha çok "erkek benzeri" olduğu bildirilmektedir. Bu çalışmanın amacı ortak özellikleri bulunan OKB ve otizm grubunun 2d:4d oranı ve parmak uzunlukları açısından karşılaştırılmasıdır. Yöntem: Bu çalışmaya 6-18 yaşları arasında olan OKB tanısı konulan 15, Yaygın gelişimsel bozukluk ( YGB ) tanısı konulan 12 ve herhangi bir psikiyatrik bozukluğu olmayan 54 erkek sağlıklı çocuk-ergen dahil edilmiştir. Hasta grubunda OKB ve YGB tanısı ayrıntılı klinik değerlendirme sonucunda DSM IV-TR tanı kriterlerine göre konulmuştur. Değerlendirme sonrasında dijital kompas yardımıyla çocuk ve ergenlerin el uzunluğu, el genişliği, parmak uzunlukları ölçülmüştür. Bulgular : Kontrol, OKB ve YGB grupları arasında sağ ve sol 2d:4d oranı yönünden istatistiksel olarak anlamlı farklılık saptanmamıştır. Buna karşın, YGB grubunda sağ el 2. ve 3.parmaklar ile, sol el 2,3,4. parmakların kontrol grubuna göre daha kısa olduğu saptanmıştır. Sol el uzunluğu YGB grubunda OKB grubuna göre daha kısa olarak saptanırken, sağ 2. ve sol 3. parmak uzunluğu YGB grubunda kontrol ve OKB grubuna göre daha kısa olarak bulunmuştur. Sonuç : Bu çalışmada 2d:4d oranı açısından OKB, YGB ve sağlıklı kontroller arasında herhangi bir farklılık saptanmazken; YGB grubunda bazı parmak boylarının kontrol grubuna göre daha kısa olduğu tespit edilmiştir. Bu bulgu YGB grubunda taranabilecek bir dismorfolojik bir bulgu olabilir ancak daha geniş örneklemlerle yapılacak ileri çalışmalara ihtiyaç duyulmaktadır. ABSTRACTObjective: Obsessive compulsive disorder (OCD) and autism share some common features, such as repetitive behaviors. Second finger to fourth finger ratio (2d: 4d) is thought to be associated with prenatal androgen exposure and differs between the sexes and 2d:4d ratio is reported to be more "masculine like features" in autism. The aim of this study is to compare OCD and autism that display common features in terms of 2d: 4d ratio and finger lengths. Methods: This study included 15 boys diagnosed with OCD, 12 boys diagnosed with Pervasive Developmental Disorder (PDD), and 54 healthy boys with no psychiatric disorders between the ages of 6 and 18 years. The diagnoses of OCD and PDD were reached after detailed clinical evaluations according to DSM IV-TR criteria. After the evaluation, the children's and adolescents' hand length, hand width, and finger lengths were measured with a digital compass. Results: In this study, we found no statistically significant difference between the control, OCD, and PDD groups regarding the right and left 2d: 4d ratio. Whereas in the PDD group, we found that the right hand second and third fingers and the left hand second, third, and fourth fingers were shorter than the fingers of those in the control group. We also found that left hand length was shorter in the PDD group than in the OCD group and the second finger of the right hand and third finger of l...

“…The sum of these points was used to determine the Geschwind Score (GS), as an indicator of the direction and degree of hand preference. Hand preference was evaluated in 5 groups depending on the value of GS, consistent righthanders: +80<GS<+100, weak right-handers: +20<GS<+75, ambidexters: −15<GS<+15, weak left-handers: -75<GS<−20, and strong left-handers: -100<GS<-80 (see Tan, 1988;Kulaksiz & Gozil, 2002).…”

178C. BARUT ET AL.(22.11 ± 2.07). Of the right-handed men, 75.5% preferred the right foot, 7.1% the left foot, and 17.4% both feet. Of ambidextrous men, 44.0% preferred the right foot, 28.0% the left foot, and 28.0% both feet. Of left-handed men, 32.3% preferred the right foot, 56.9% the left foot, and 10.8% both feet. The differences between these percentages were found to be statistically significant. Of the right-handed women, 89.9% preferred the right foot, left foot 1.2%, both feet 8.9%, whereas 50.0% preferred the right foot, 12.5% the left foot, and 37.5% both feet in the ambidextrous women. In the left-handed women, 8.8% preferred the right foot, 79.4% the left foot, and 11.8% both feet. The differences between these percentages were found to be statistically significant. The results suggested that the cultural differences among the different study groups may be the reason for the inconsistencies with regard to hand and foot preferences. Moreover, the results may bring insight into the foot preference in relation to hand preference in the Turkish population.
